JOHN B. STANHOPE, OF PHILADELPHIA, PENNSYLVANIA.

BARREL-TRUSSING MACHINE.

A SPECIFICATION forming part of Letters Patent No. 514,738, dated February 13, 1894. Application 1111111 May 25, 1893. $111111 n11. 475,459. (N11 111111111.)

To all whom it may concern.-

Be it known that I, JOHN B. STANHOPE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Barrel-Trussing Machines, of which the following is a specification.

One object of my invention is to so constrncta barrel trussing machine as to dispense with the separate bilge hoops usually employed, and a second object is to automatically trip the barrel retainer after the hoop driving devices have been retracted. These objects I attain in the manner hereinafter set forth,- reference being had to the accompanying drawings, in which- Figure 1, is a side view of sufficient of a barrel trussing machine to illustrate my invention; and Fig. 2, is a transverse section of part of the machine on the line 2-2 Fig. 1.

A and B represent the two driving heads which are suitably guided on the fixed frame of the machine, each head having a projecting centering drum or and a pusher b for act- 1ng on the truss hoops at the ends of the barrel, the heads being caused to move in oppo-' site directions by means of cranks on the shaft D, one of these cranks being connected directly to the head A and the other being connected to a cross head F which is connected by rods d to the driving head B, the cranks of the shaft D being so set that as said shaft is rotated the driving heads A and B will be caused to approach and recede from each other. All of these parts are similar to those of well known machines, in which, however, each of the driving heads A and B is furnished with projecting bolts f carrying plungers for forcing on bilge hoops which have been previously applied to the barrel and which must be removed after the trnssing of the barrel has been completed, the handling of these hoops being a considerable item of expense in the cost of manufacture of the barrel. In place, therefore, of these plungers I provide the bolts f of the heads A and B with truss rings G which, as the driving heads are moved inward, are'forced onto the bilge of the barrel and take the place of the bilge hoops, the rings being withdrawn on the retraction of the driving heads, leaving the staves of the barrel to be held in place by the truss hoops at the ends of the same.

In order to prevent the barrel from being drawn to one side or the other by either driving head as the latter is retracted, it is usual to employ a hooked catch or retainer such as shown at I, for instance, this retainer engaging with the ends of the barrel or with the end truss hoops and serving to hold the barrel in a central position while the driving heads are being retracted, the retainer, however, being .hung to one of the bars of the frame so that it can be lifted to release the barrel and permit the same to roll out of the machine. Each of the bilge rings Gis, therefore, slotted, as shown in Fig. 2, forthe reception of this retainer, and eachring is provid ed with a curved guard z' in which said retainer can play as it is raised and lowered.

In order to provide for the automatic op-- eration of the retainer,I connect thereto one end of a cord or wire m which, after passing around suitable guide pulleys n, is connected to the cross head F so that when the latter moves forward in order to retract the driving head B, the retainer I'will be lifted in order to discharge the barrel, the cord or wire having such'slack that-the catch will not be lifted until the centering drums a are clear of the barrel and the latter is free to roll out of the machine. It will be evident that the same result might be attained by suitably connecting the cord'm to either of the headsA or B.

The bilge rings G are slotted as shown at s, Fig. 2, for the reception of the bars of the supporting frames M upon which the barrel rests while it is being .trussed. These supporting frames form no part of my present invention and asthe manner of constructing and mounting the same is shown in prior patents, for instance in Holmes patent, No. 241,139, dated May 10, 1881, further illustration of them in this case will be unnecessary. Having thus described my 1 invention, I claim and desire to secure by Letters Pat ent- 1 1.
